Specification of Letters Patent.

Patented May 7, 1907.

Application filed January 24, 1906. Serial No. 297,550.

To all whom, it may concern:

Be it known that I, DAVID FRANKLIN STAKES, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Apparatus'for Registering Telephonic Calls, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to devices arranged to register the number of outgoing calls from a subscribers station.

It is the object of my invention to provide a registering device whereby the subscriber may independently register his calls on an instrument local to his set, but connected to indicate to the operator that such a call has been registered.

My invention comprises a sectional drum whose sections are geared to rotate in a decimal-relation, and on whose periphery digits are displayed, a lever arranged to successively shift said digits, and thus register successive calls and, means arranged to return said lever to its normal position and make and break the circuit to indicate to the operator that a call has been registered.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings, Figure I, is a front elevation, showing a registering device embodying my improvements, applied to' a subscribers telephone set. Fig. II, is a lan sectional view, taken on the line II, II, in Fig. I, but showing the full size of said registering device. F III, is a side elevation of the registering device, as seen from the left hand side of Fig. II. Fig. IV, is a side elevation, similar to Fig. III, but with the casing of the registering device removed. Fig. V, is an elevation of the registering device, as seen from the left hand side of Fig. IV. Fig. VI,

is a transverse vertical section of the register 111g device, exclusive of its casing, taken onthe line V I, V I, in Figs. II, and V. Fig. VII, is a wiring diagram showing a convenient arrangement of the registering device in relation to a subscribers'set.

In said figures; 1, is the portable casing base, 2, the transmitter, and 3, the receiver of a subscribers telephone set of ordinary,

construction. The registering device is inclosed in the casing 5, secured to said base 1,

and comprises a sectional drum 6, whose sectlons are lnternally geared according to a well known decimal system and have digits displayed upon their peripheries arranged to indicate through the slot 8, in the casing 5, the number of calls registered. Said sectional drum 6, is arranged to be intermittently rotated by the oscillatory handle lever 10, which is normally s ring pressed to the position shown in the Lrawmgs, and which carries the sector 11, arranged to mesh with the lantern gear 12, upon the shaft .13. Said shaft 13, is journaled in the frame 14, and carries the escapement wheel 15, whose teeth are engaged by the pallets of the escapement pawl lever 17. Said pawl 17, is rigidly secured on the shaft 19, which is journaled for oscillation in theframe 1 4, and provided with the lever 20, arranged to makeand break electrical contact withthe arm 22, which is secured in the insulated bushing 23, in the frame 14, and connected by the wire 24, with the contact plate 25, so as to be included in parallel relation with the transmitter 2, as indicated in Fig- V II.

The shaft 13, is arranged to be rotated independently of the escapement wheel 15, in the direction of the arrow indicated in Fig. VI, but is arranged to turn said escapement wheel 15, when rotated in the opposite direction by the engagement of its lug 27, with the pawl 28, carried by said wheel, as shown in Fig. VI said pawl 28, being normally pressed toward said shaft by the spring 29.

The registering operation is as follows The subscriber desiring to make a call,lifts the receiver 3, from the hook 4, and, the op erator having obtained connection with the party desired, requests the subscriber to register, which is accomplished by pressing the device, the operator connects the subscribers line with the party desired.

It may be observed that the automatically transmitted signal above described as audible at the central station, may also be'manitested by the ordinary visual signaling devices at said station.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from. the essential features of my invention.

I claim i 1. In apparatus for registering telephonic calls, the combination with a numerical regis tering device, comprising a series of indicator disks, arranged to rotate on a common axis of a handle mounted to rotate on said axis and arranged to shift said disks; a countershaft comprising a pinion in parallel relation to said axis; a sector carried by said handle,

and arranged to engage said pinion; an escapement wheel on said countershaft and escapement in operative engagement with said wheel; a stationary contact; an electric circuitincluding said stationary contact and said escapement; and a contact carried by said escapement arranged to oscillate into and out of engagement with said stationary contact to make and break said circuit, and thereby transmit a signal indicating .that

handle has been operated, substantially as set forth.

2. In apparatus for registering telephonic calls, the combination with a numerical registering device, comprisinga series of disks having numerals on their periphery and arranged to rotate on a common axis of a handie mounted to rotate on said aXis and a1 ranged to'shift said disks; a sector carried by said handle a countershaft in parallel relation to said axis a pinion mounted on said counter shaft and arranged to engage said sector; an escapement operatively related to said handle a stationary contact; a movable contact carried by said escapement; and an electric circuit including said stationary contact and said escapement, whereby the movement of said escapement causes the movable contact to oscillate into and out of engagement with said stationary contact to make and break said circuit, and thereby transmit a signal indicating 'that said handle has been operated, substantially as set forth.

3. In apparatus for registering telephonic calls, the combination with a numerical registering device comprising an escapement of a countershatt having a pinion mounted thereon; a handle mounted. torotate and having a sector arranged to engage said pinion,

said handle being operatively connected to said registering device; a stationary contact; a movable contact carried by said escapement; and an electric circuit including said escapement whereby the movement of said handle operates said escapement to make and break said circuit to transmit a signal indicating that said handle been operated, substantially as set'forth.

In testimony whereof, I have hereunto signed my name, at Philadelphia, Pennsyl- Vania, this 22nd day of January, 1906.
